Input range is VRB to VRT (0 to 1.5 V) Relationship between analog input and digital output is defined by Test function. Input pin for reference voltage adjustment amp (VRT reference voltage adjustment) VRT is adjusted so that it is 1.5 V with the input pin opened. Reference voltage output pin on top side. The voltage fed to VRTC is output. Reference voltage input pin on bottom side (0V) Input pin 1 for 1:3 gain amp Input pin 2 for 1:3 gain amp Dual input selector for inverting amp
Input pin for 1:3 gain (at standby: high impedance) Toggle input pin for dual input selector for 1:3 gain amp Input "L": VIN1, Input "H": VIN2 Input pin for toggling standby function. Input high signal brings the standby state to the A/D converter, 1:3 gain amp, and reference voltage adjustment amp. Output (D7 to D0) enable input pin. Input low signal readies digital output. Input high signal induces high-impedance state. Test input pin. No connection pins

s PRECAUTIONS ON USE
Be sure to ground the pins of AVDD5, AVDD3, DVDD and VRT via high-frequency capacitor. Place the high-frequency capacitor as close as possible to the pin. You can minimize the power supply current dissipation due to the internal logic indetermination by making CE to high on power turning on.
